A preliminary police report indicates San Miguel was driving along Loop 410 at Perrin Beitel Road when he ran a red light and rear-ended two vehicles.

Sgt. Scott Foulke said San Miguel was unresponsive at the scene and was rushed to an area hospital, adding that it's possible a medical episode of some sort contributed to him running the light and crashing.

San Miguel was the father of five children, including Van de Putte, D-San Antonio, who since 1991 has represented a large portion of San Antonio and Bexar County, first as a state representative and now a state senator.

The death of her father comes less than two months after her infant grandson, Rex Van de Putte, died suddenly of natural causes in early May.
